Whilst sat in traffic today, my V-reg X16SZR (1.6 8v) decided to overheat quite dramatically.
Upon inspection, the fan was running and the rad was hot, so I assume the 'stat had opened? I've checked all the pipes and the water seems to be circulating ok and I don't appear to be losing any water.
Now it over heats constantly (it's not being driven just checked on ).
My first thoughts are head gasket, water pump or even a blocked rad but as the cooling systems appears to operating properly it has baffled me.
I'd really appreciate any suggestions.
